One further question I forgot to ask -- would you place the use
of forwarding in the same category as using wildcard records,
especially wildcard MX records?
In other words, no one should ever publicly advocate their use,
and all public mention of them should discourage everyone from using
them, but sufficiently knowledge-able people (who know who they are
;-) will know when they can violate this rule?
